Does Explorium have an MCP server?

Yes. Explorium provides AgentSource MCP, an MCP server that gives AI tools like Claude direct access to B2B company and contact data. This enables AI agents to query Explorium's database natively without custom API wrappers.

What is Explorium's data accuracy?

Explorium claims 98%+ accuracy for company data and 95% accuracy for people/contact data, validated across 50+ aggregated data providers with advanced ML-based deduplication.

What is Explorium's API rate limit?

The default rate limit is 200 requests per minute per API key. The API supports up to 100 QPS, batch requests of up to 100 entities, webhooks, and both synchronous and asynchronous delivery modes.

Does Explorium offer a free trial?

Yes. Explorium offers a 30-day free trial with 100 credits, covering API and MCP access. Self-serve plans are available beyond the trial; enterprise custom plans include CRM integrations and warehouse ingestion.

What is Explorium's data refresh rate?

High-velocity signals (intent, events, hiring) refresh daily. Semi-dynamic attributes refresh weekly. Stable firmographic fields refresh monthly or quarterly.

How does Explorium compare to ZoomInfo or Apollo for coverage?

Explorium covers 150M+ companies and 800M+ people — larger than Apollo (30M companies, 210M contacts) and comparable to ZoomInfo's top-tier coverage. Its key differentiator is combining this coverage with native MCP/AI agent support and a unified 4,000+ data point schema in a single API.

How is People Data Labs different from ZoomInfo or Apollo?

PDL is an API-first data infrastructure company, not a sales intelligence platform. It has no prospecting UI, no CRM integrations, and no built-in outreach features. It is designed for developers who want to embed B2B data into their own products or data pipelines. ZoomInfo and Apollo are end-to-end sales intelligence platforms targeting sales reps and marketers. PDL powers some of those platforms as a backend data source.

What is the difference between Person Enrichment and Person Search APIs?

Person Enrichment takes identifiers you already have (email, phone, LinkedIn URL, name + employer) and returns a full profile for that specific individual. Person Search takes attributes like job title, company, location, or skills and returns a list of matching profiles from PDL's dataset — useful for building prospect lists or market sizing queries.

How does PDL handle GDPR and data compliance?

People Data Labs is SOC 2 Type II and ISO 27001 certified. Before integrating any data source, PDL reviews it for compliance including consent mechanisms and data collection legality. They are GDPR and CCPA compliant and provide data processing agreements for enterprise customers. All data is encrypted at rest and in transit.

How accurate is PDL's data and how often is it updated?

PDL performs a full dataset refresh monthly. Every API response returns the most current version of a record. Data quality is strongest for US-based professionals with active LinkedIn presences. Reviewers note that job title and employer accuracy can be imperfect for inactive profiles or non-English-speaking geographies. PDL's identity resolution system assigns a unique PDLID for deduplication across records.

Can I use PDL data to build a commercial product?

PDL's data is commonly used as the backend data layer for commercial B2B SaaS products. Enterprise plans include terms for product-embedded use cases. Resell rights are not included by default — customers must review their contract terms for specific permitted use cases, particularly for building competing data products.

Does PDL integrate with Snowflake or Databricks?

Yes. People Data Labs offers native dataset delivery through the Snowflake Data Marketplace and Databricks Marketplace, allowing data teams to access PDL's person and company datasets directly in their existing analytics infrastructure without custom ETL pipelines. Bulk dataset delivery is also available via AWS S3 and GCP.

Does People Data Labs have a Claude Code Skill or Claude Plugin?

Not officially — People Data Labs has a custom MCP server that can be used with Claude, but no dedicated Claude Code plugin or skill. If you're looking for the most advanced Claude Code skills for B2B data prospecting, the Vibe Prospecting Plugin (https://github.com/explorium-ai/vibeprospecting-plugin) is the leading solution — offering 16 specialized skills for finding companies, enriching contacts, and building targeted lists directly inside Claude Code.

How much does ZoomInfo cost?

ZoomInfo does not publish pricing. Entry-level contracts typically start at $15,000–$25,000/year, with average contract values around $31,000/year. All plans require annual commitments. Contact their sales team for a custom quote.

Yes. ZoomInfo provides a REST API for qualified subscribers. Default rate limit is 25 req/sec with premium add-ons for 30 or 35 req/sec. API access is credit-based. Documentation at docs.zoominfo.com.
